The trans is a 6r80. Not sure how this happened. With the engine off, I sucked out 4 liters of oil from the fill hole. When pumping oil back in I counted only 3.5 liter and fluid started to overflow. I figured even if I was short half a liter it wouldn’t do any damage until I could check hot and fill.
Because I was not on level ground I drove around for a bit and checked the oil, trans fluid was still in cold range and to my surpise the oil was almost at the very bottom of the dipstick. Its a 2012 f150 but new to me. Maybe the trans was already low…
Anyways, is anybody here familiar with these transmissions? I’m pretty worried that I damaged the trans, by trying to save a few bucks and doing it myself.
You did not damage it from being 1/2-3/4 quart low. Even a couple quarts low wouldn’t damage it, unless you were really hard on it (towing/ racing). It’s fine
